Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a comprehensive surgical manipulator for ocular surface surgery. Background Technology

[0002] In the field of ocular surface surgery, whether it's organic repair surgeries like pterygium excision and corneal transplantation, or postoperative care after severe ocular surface infections, meticulous management of the surgical area remains a core factor determining surgical prognosis. Ocular surface tissues (such as corneal epithelium and conjunctival tissue) are fragile and highly sensitive. During surgery, three key objectives must be achieved simultaneously: first, maintaining continuous cleanliness of the surgical field by promptly removing intraoperative bleeding, tissue debris, and secretions to prevent contaminants from affecting wound healing; second, ensuring precise drug delivery, especially for cytotoxic drugs like mitomycin C or immunomodulators like cyclosporine, requiring strict control of dosage and application to prevent damage to normal tissues; and third, minimizing secondary irritation to the ocular surface during the procedure, avoiding epithelial abrasions or mucosal damage caused by physical contact. Achieving these objectives directly impacts postoperative infection rates, restoration of corneal transparency, and patient visual prognosis, making them a core focus for medical professionals performing ocular surface surgery.

[0003] Currently, ocular surface surgery still relies on the traditional "manual alternation of multiple instruments" model: doctors need to use a syringe to rinse with saline, wipe the wound with sterile cotton swabs or apply medication, and then use a suction device to remove waste fluid and secretions from the surgical area. In some cases, additional auxiliary instruments such as micro forceps are also required. To improve ease of operation, although improved instruments (such as suction devices with side-hole irrigation) have been introduced, these instruments only achieve a simple combination of "rinsing + suction" functions and do not fundamentally change the nature of "single instrument, single function". During operation, it is still necessary to frequently adjust hand posture to adapt to the grip requirements of different instruments, and they cannot be compatible with key steps such as medication application. At the same time, the head shape of these improved instruments is fixed, making it difficult to adapt to the delicate operation of narrow anatomical areas such as the pericorneal region and inner canthus. When facing the personalized needs of different surgical procedures (such as pterygium excision vs. amniotic membrane coverage), doctors still need to manually adjust the operating force and angle.

[0004] The shortcomings of existing operating procedures have become a key bottleneck restricting the improvement of ocular surface surgery quality: First, inefficiency and unstable surgical field are prominent issues; instrument switching interrupts an average of 8-15 times per surgery, which not only prolongs the operation time but may also lead to decreased surgical field clarity due to the accumulation of secretions during interruptions, increasing the risk of misoperation. For example, when dealing with peripheral corneal hemorrhage, switching from a suction device to a syringe for irrigation may miss the optimal time for hemostasis, leading to postoperative corneal edema. Second, the risks of cross-contamination and tissue damage are significant; when wiping with cotton swabs, fibers are easily shed and remain in the surgical area, and can spread bacteria (such as Staphylococcus) and abnormal cells (such as pterygium cells) from the ocular surface to healthy corneal areas. Clinical data shows that the postoperative infection rate of ocular surface surgery using cotton swabs is about 1.2%, significantly higher than other types of ophthalmic surgery. At the same time, the physical wiping force of cotton swabs is difficult to control precisely. First, the procedure is prone to causing scratches on the fragile ocular surface epithelium after surgery, prolonging the patient's recovery period. Second, there is low drug utilization and dosage control. When administering medication via eye drops or cotton swabs, only 5%-10% of the solution can act on the target tissue, with the remainder being washed away by overflow and tears. When manually applying medication, the dosage is affected by the doctor's hand strength and application time, with dosage differences of more than 30% between different times of the same operation. For drugs like mitomycin C, which require strict dosage control, dosage deviations can easily lead to corneal toxicity. Third, there is low standardization. Surgical results rely excessively on the doctor's personal experience. Experienced doctors can reduce errors through skillful operation, but novice doctors, due to insufficient control over instruments, are prone to problems such as excessive irrigation pressure damaging the cornea and accidental aspiration of tissue during suction. This results in poor consistency of surgical results between different doctors or between different times of the same doctor, making it difficult to establish unified diagnostic and treatment standards. Therefore, there is an urgent clinical need for a modular operating platform that can integrate multiple functions, adapt to personalized surgical procedures, and achieve precise control, in order to overcome the limitations of existing technologies and improve the safety, efficiency, and standardization of ocular surface surgery. Summary of the Invention

[0005] In view of this, the purpose of this invention is to propose a comprehensive operating device for ocular surface surgery. This device integrates a central controller, a precision fluid drive module, an automatic identification function, and preset surgical modes into a universal host unit; a disposable operating handpiece with a quick-connect interface, a built-in chip, and a magnetic connection mechanism; a replaceable disposable functional head including a standard rinsing and suction head, a precision operating head, a curved head, and a brush head that can replace cotton swabs; and a matching high-definition touchscreen, an external foot switch, and a pressure sensor safety closed-loop control system. This integrated system solves the problems in existing ocular surface surgery, such as low operational efficiency due to dispersed instruments, cross-contamination and damage to ocular surface tissues caused by cotton swab use, insufficient accuracy and low utilization of drug administration, and excessive reliance on physician experience and lack of standardized operating procedures.

[0006] This invention is achieved through the following technical solution:

[0007] A comprehensive surgical manipulator for ocular surface surgery includes a universal main unit, a disposable operating handpiece, and a replaceable disposable functional head. The universal main unit internally houses a central controller and a precision fluid drive module. The central controller is electrically connected to the precision fluid drive module via wiring. Externally mounted on the universal main unit is a user control interface electrically connected to the central controller via wiring. A quick-connect port is fixedly located on the lower front of the universal main unit, connected to the precision fluid drive module via fluid tubing, and also electrically connected to the central controller via wiring. The disposable operating handpiece has a quick-connect interface at its tail, which is detachably connected to the quick-connect port. A built-in chip is fixedly attached to the inner side of the quick-connect interface at the tail of the disposable operating handpiece. The built-in chip is connected to the metal contacts on the end face of the quick-connect interface via a wire. The front end of the disposable operating handpiece has a magnetic connection mechanism, and the replaceable disposable functional head is detachably connected to the disposable operating handpiece via the magnetic connection mechanism. The disposable operating handpiece has a fluid channel and a suction channel along the axial direction inside, and an isolation wall is provided between the fluid channel and the suction channel.

[0008] Furthermore, the central controller has a built-in pre-stored set of various surgical mode parameters. The central controller has an automatic identification function. The central controller interacts with the built-in chip through the quick docking port to identify the type of the disposable operating hand and the replaceable disposable functional head, and calls up the surgical mode parameters that match the type.

[0009] Furthermore, the precision fluid drive module includes a multi-way solenoid valve, a high-precision drug delivery peristaltic pump, a suction peristaltic pump, and a pressure sensor. The inlet of the multi-way solenoid valve is detachably connected to an external drug bag via a sterile silicone tube. The outlet of the multi-way solenoid valve is connected to the inlet of the high-precision drug delivery peristaltic pump via a corrosion-resistant hose. The inlet of the suction peristaltic pump is detachably connected to a negative pressure collection device via a tube with a filter structure. The pressure sensor is fixed to the suction line between the suction peristaltic pump and the quick docking port via a threaded interface with a sealing gasket. The pressure sensor is electrically connected to the central controller via a circuit to form a safe closed-loop control.

[0010] Furthermore, the user control interface includes a high-definition touchscreen and an external foot switch. The high-definition touchscreen is embedded and fixed on the upper front of the general-purpose host and is electrically connected to the central controller via a ribbon cable. The external foot switch is detachably connected to a USB interface on the side of the general-purpose host via a USB cable and is electrically connected to the central controller via a circuit. The external foot switch has three positions: "rinse / suction", "administer medication", and "stop".

[0011] Furthermore, the handle of the disposable operating tool is provided with anti-slip textured surfaces, and the magnetic connection mechanism includes an annular magnet and positioning protrusions. The annular magnet is embedded and fixed in the end face of the front end of the disposable operating tool, and the positioning protrusions are evenly distributed on the outer side of the annular magnet along its circumference, and the positioning protrusions are fixedly connected to the end face of the front end of the disposable operating tool.

[0012] Furthermore, the tail of the replaceable disposable functional head is provided with a metal ring and a positioning groove. The metal ring is embedded and fixed in the end face of the tail of the replaceable disposable functional head. The metal ring is magnetically attracted to the annular magnet. The positioning groove is evenly distributed on the inner side of the metal ring along the circumference. The positioning groove is engaged and positioned with the positioning protrusion.

[0013] Furthermore, the replaceable disposable functional head includes a standard rinsing and suction head, a fine operation head, an elbow, and a brush head. The standard rinsing and suction head has a central rinsing tube and a suction ring cavity inside. The central rinsing tube is connected to the fluid channel, and the suction ring cavity is connected to the suction channel. The distal end of the brush head is integrated with medical silicone bristles. The brush head has a drug storage cavity inside. The drug storage cavity is connected to the fluid channel. A miniature solenoid valve is installed in the drug storage cavity. The miniature solenoid valve is electrically connected to the central controller through a circuit.

[0014] Furthermore, when the pressure sensor detects that the pressure in the suction line exceeds a preset threshold, the central controller sends a control signal through the line to reduce the speed of the suction peristaltic pump; if the pressure continues to exceed the threshold, the central controller controls the suction peristaltic pump to stop working and displays alarm information through the high-definition touch screen, while simultaneously triggering the prompt sound generator on the side of the general host.

[0015] Furthermore, the general-purpose host is equipped with a metal mounting bracket, on which rubber shock-absorbing pads are attached. The central controller is fixed to the left side of the mounting bracket via conventional connectors, and the precision fluid drive module is fixed to the right side of the mounting bracket via conventional connectors. The general-purpose host has heat dissipation holes on its sides and back, and dustproof meshes are fixed inside the heat dissipation holes.

[0016] The beneficial effects of this invention are as follows:

[0017] This invention establishes a modular ocular surface surgery platform that integrates intelligent control, multi-functional adaptation, and safety protection. Its dedicated functional head, which can replace traditional cotton swabs, helps prevent cross-contamination and avoid secondary damage to ocular surface tissues. A universal host with automatic recognition and preset surgical modes simplifies the operation process, improves surgical standardization, and reduces reliance on physician experience. A safety closed-loop control system built with pressure sensors helps mitigate operational risks in real time and ensure surgical safety. Overall, this invention simultaneously improves the efficiency, accuracy, and safety of ocular surface surgery, reducing the workload of medical staff. Attached Figure Description

Detailed Implementation

[0026] like Figures 1 to 6 As shown, this embodiment provides a comprehensive surgical manipulator for ocular surface surgery. One embodiment includes a universal host 1, a disposable operating handpiece 2, and various replaceable disposable functional heads 3.

[0027] The general-purpose main unit 1 is a trolley-type design, with its internal core components fixed by a mounting bracket. Rubber shock-absorbing pads are attached to the surface of the mounting bracket to buffer vibrations.

[0028] The central controller 11 is fixed on the left side of the mounting bracket and is connected to the precision fluid drive module 12, user control interface 13, quick docking port 14 and prompt tone generator 15 via cables. It is the control core of the entire platform and is responsible for parameter calling, component linkage and abnormal handling.

[0029] The precision fluid drive module 12 is fixed on the right side of the mounting bracket and includes a multi-way solenoid valve 121, a high-precision drug delivery peristaltic pump 122, a suction peristaltic pump 123, and a pressure sensor 124. The multi-way solenoid valve 121 is located at the top, with its inlet connected to an external drug bag via a pipeline and its outlet connected to the inlet of the high-precision drug delivery peristaltic pump 122 via a hose. The high-precision drug delivery peristaltic pump 122 is located below the multi-way solenoid valve 121, with its outlet connected to the fluid interface of the quick docking port 14 via a hose. The suction peristaltic pump 123 is located to the right of the high-precision drug delivery peristaltic pump 122, with its inlet connected to an external negative pressure collection device via a pipeline with a filter, and its outlet leading to a waste liquid discharge port. The pressure sensor 124 is installed on the suction pipeline between the suction peristaltic pump 123 and the quick docking port 14, and is connected to the central controller 11 via a line to provide real-time feedback of the pipeline pressure to form a safe closed loop.

[0030] The user control interface 13 includes a high-definition touch screen 131 and an external foot switch 132: The high-definition touch screen 131 is embedded in the upper front of the general host 1 and connected to the central controller 11 via a ribbon cable. It is used to display status, select modes, and adjust parameters. The external foot switch 132 is connected to the side interface of the general host 1 via a USB cable and then connected to the central controller 11 via a line. It has three positions: "rinse / suction", "administer medication" and "stop", which are triggered for aseptic operation during surgery.

[0031] The quick docking port 14 is located on the lower front of the general host 1. One end is connected to the precision fluid drive module 12 (high-precision drug delivery peristaltic pump 122, suction peristaltic pump 123) through a fluid pipeline, and the other end is connected to the central controller 11 through a line. It is used to dock with the disposable operating handpiece 2 to realize fluid transmission and signal interaction.

[0032] The prompt tone generator 15 is installed on the side of the general host 1 and is connected to the central controller 11 via a line. It emits a prompt tone when the mode is confirmed or the pressure is abnormal. The general host 1 has heat dissipation holes on the side and back, and dustproof screens are installed in the heat dissipation holes for heat dissipation and dust prevention.

[0033] The disposable hand tool 2 is shaped like a pen, and the handle has anti-slip textures 23 to improve grip stability.

[0034] The tail is provided with a quick docking interface 21, which can be detachably connected to the quick docking port 14 of the general host 1. An internal chip 211 is attached to the inside of the interface. The internal chip 211 is connected to the metal contacts on the end face of the interface through wires. When the interface is inserted into the quick docking port 14, the metal contacts make contact with the contacts inside the port, realizing the signal interaction between the internal chip 211 and the central controller 11 for identifying the type of handpiece.

[0035] The front end is provided with a magnetic connection mechanism 22, including a ring magnet 221 and a positioning protrusion 222: the ring magnet 221 is embedded in the front end face, and the positioning protrusion 222 is evenly distributed on the outer side along the circumference of the ring magnet 221, for connecting with the replaceable disposable functional head 3.

[0036] The interior is provided with a fluid channel 24 and a suction channel 25 along the axial direction. The two channels are separated by an isolation wall 26 to prevent fluid mixing. One end of the fluid channel 24 is connected to the fluid interface of the quick docking interface 21, and the other end is connected to the front magnetic connection mechanism 22 for conveying medicine or rinsing fluid. One end of the suction channel 25 is connected to the suction interface of the quick docking interface 21, and the other end is connected to the front magnetic connection mechanism 22 for suctioning waste liquid.

[0037] The disposable operating tool 2 is packaged in double-layer aseptic packaging. A humidity indicator card is placed inside the packaging to monitor the aseptic status. An easy-tear notch is provided on one side of the packaging for quick opening and use.

[0038] Various replaceable disposable functional heads 3 are equipped with a metal ring 31 and a positioning groove 32 at their tails. The metal ring 31 is magnetically attracted to the annular magnet 221 of the disposable operating handpiece 2, and the positioning groove 32 is fitted with the positioning protrusion 222 for positioning, ensuring a stable connection and accurate positioning. The specific types and structures are as follows:

[0039] Standard irrigation and suction head 33: The interior has a dual-chamber design. One end of the central irrigation tube 331 is connected to the fluid channel 24 of the disposable operating handpiece 2 for spraying irrigation fluid or medicine; one end of the outer suction ring cavity 332 is connected to the suction channel 25 for suctioning waste fluid from the surgical area, which is suitable for routine irrigation and suction scenarios.

[0040] Fine operation head 34: The head diameter is smaller than that of the standard irrigation and suction head 33. It is cone-shaped and has two internal cavities that connect the fluid channel 24 and the suction channel 25 respectively, making it suitable for operation in narrow spaces such as the corneal periphery and lacrimal punctum.

[0041] The elbow 35 is bent at a preset angle with a smooth transition at the bend. The internal double cavity is connected to the fluid channel 24 and the suction channel 25 respectively, which is suitable for operation on anatomical parts that are difficult to see directly, such as the inner canthus.

[0042] The brush head 36 has medical silicone bristles 361 integrated at the distal end for uniformly applying the medicine; it has a medicine storage chamber 362 inside, one end of which is connected to the fluid channel 24 to receive the medicine; a miniature solenoid valve 363 is installed in the chamber and is connected to the central controller 11 through a circuit (conducted through the metal ring 31 and the annular magnet 221). The central controller 11 controls the opening and closing of the solenoid valve to achieve precise release of the medicine.

[0043] In this embodiment, the power supply of the general host 1 is first turned on, and the central controller 11 automatically starts the self-test program, sequentially testing the status of the precision fluid drive module 12 (multi-way solenoid valve 121, high-precision drug delivery peristaltic pump 122, suction peristaltic pump 123, pressure sensor 124), the user control interface 13 (high-definition touch screen 131, external foot switch 132), and the quick docking port 14. After the self-test passes, the high-definition touch screen 131 displays "ready". In case of failure, the code and troubleshooting suggestions are displayed.

[0044] Connect the external medicine bag (such as physiological saline or drug diluent) to the inlet of the multi-way solenoid valve 121 through a pipeline, and connect the external negative pressure collection device to the inlet of the suction peristaltic pump 123 through a pipeline with a filter screen, ensuring that the pipeline is free of bends and leaks.

[0045] Unpack the disposable operating tool 2 through the easy-tear notch, insert the quick-connect interface 21 at its tail into the quick-connect port 14 of the universal host 1, the built-in chip 211 interacts with the central controller 11, and the high-definition touch screen 131 displays the tool type; select the appropriate functional head 3 (such as the standard rinsing suction head 33), and complete the connection with the disposable operating tool 2 by magnetic attraction between the metal ring 31 and the annular magnet, and by the engagement of the positioning groove 32 and the positioning protrusion 222. The central controller 11 automatically identifies the functional head type and displays it.

[0046] Clicking on the high-definition touchscreen 131 to select "surgical mode" (such as "pterygium removal mode") will cause the central controller 11 to call up pre-stored parameters (such as irrigation flow rate, suction pressure, and drug dosage), which will be displayed on the high-definition touchscreen 131 in real time.

[0047] If you need to customize the parameters, click "Advanced Settings" and adjust the parameters (such as flushing flow rate 1-10 mL / min, suction pressure -0.01 to -0.05 MPa) using the slider on the high-definition touchscreen 131. After adjustment, click "Save" and the central controller 11 will store the parameters and update the display.

[0048] Clicking "Confirm Mode" will trigger a beep from the prompt tone generator 15, and the external foot switch 132 will enter standby mode, indicating that the platform is ready.

[0049] The doctor holds a disposable operating tool 2, aligns the standard irrigation and suction head 33 with the surgical area, and presses the "irrigation / suction" position on the external foot switch 132. The central controller 11 is triggered simultaneously: the multi-way solenoid valve 121 opens the corresponding drug channel, and the high-precision drug delivery peristaltic pump 122 delivers the drug at a preset flow rate, which is sprayed onto the surgical area through the fluid channel 24 and the central irrigation tube 331; at the same time, the suction peristaltic pump 123 starts, generating a preset negative pressure, and the waste fluid in the surgical area is sucked in through the suction ring cavity 332 and the suction channel 25 and transported to the negative pressure collection device.

[0050] Pressure sensor 124 monitors the pressure in the aspiration tubing in real time. If the pressure exceeds the threshold (e.g., when tissue is aspirated), the central controller 11 immediately reduces the speed of the aspiration peristaltic pump 123 to reduce the negative pressure. If the pressure still exceeds the threshold, the central controller 11 controls the aspiration peristaltic pump 123 to pause, the prompt tone generator 15 emits an alarm sound, and the high-definition touch screen 131 displays "Pressure abnormality". After the doctor adjusts the pressure, clicking "Restore" will restart the pump.

[0051] When medication (such as mitomycin C) needs to be applied, remove the standard rinsing suction head 33 and replace it with the brush head 36. The central controller 11 will automatically switch to the "medication mode". Press the "medication" position on the external foot switch 132. The central controller 11 will control the micro solenoid valve 363 to open. The medication in the medication storage chamber 362 will soak the medical silicone brush bristles 361. The doctor will lightly touch the surgical area with the brush bristles. The central controller 11 can simultaneously start the micro vibration motor (a conventional component, without number) built into the disposable operating handpiece 2 to assist in the even application of the medication. Release the foot switch, and the micro solenoid valve 363 will close, stopping the medication application.

[0052] If a functional head needs to be replaced (e.g., switching back from the brush head 36 to the standard rinsing suction head 33), the current functional head can be removed directly, and the new functional head can be magnetically attached. The central controller 11 automatically identifies the type of the new functional head and switches to the corresponding mode. There is no need to reset the parameters, achieving a seamless connection.

[0053] After the surgery, step on the "stop" position of the external foot switch 132. The central controller 11 controls the multi-way solenoid valve 121 to close and the high-precision drug delivery peristaltic pump 122 and aspiration peristaltic pump 123 to stop working. The high-definition touch screen 131 displays "Surgery completed, do you want to empty the tubing?". Click "Yes", and the central controller 11 controls the aspiration peristaltic pump 123 to run in reverse for 3 seconds to expel the residual drug solution, and then run in forward for 5 seconds to aspirate the waste liquid from the tubing. After completion, it displays "Tubing emptying completed".

[0054] Remove the disposable operating tool 2 and the used functional head 3, and put them into a medical waste bag; disconnect the tubing from the medicine bag and the negative pressure collection device; after disinfecting the waste liquid bucket according to the specifications, empty the waste liquid and replace it with a new tubing for future use.

[0055] Wipe the surface of the high-definition touch screen 131, quick docking port 14 and universal host 1 with 75% alcohol, turn off the power switch, unplug the power plug, and the operation is complete.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
